  Adjusting pressure method for automatic pressure switch of piston air compressor

  1, the adjustment of pressure high and low: the pressure adjustment screw 1 clockwise, the action pressure rises, conversely, the action pressure is reduced, but the pressure difference is constant.

  2, the adjustment of pressure high and low: the pressure adjustment screw 2 clockwise, the action pressure rises, conversely, the action pressure is reduced, but the pressure difference is constant.

  3, when the air compressor operation to set pressure, then the valve will be saturated and the gas discharge tube, this is a normal phenomenon does not leak.

  4, 1-2 adjust the screw to relate to each other.

  5, adjust the pressure to exceed the compressor and set the exhaust pressure.

  Working principle of pressure switch on air compressor

  The pressure switch used in air compressor above is mainly to adjust the air compressor start stop state, by adjusting the pressure inside the tank to make the air compressor stop to rest, can maintain the machine. When the air compressor plant commissioning, according to the customer need to adjust to the specified pressure, and then set a pressure difference. For example, the compressor starts to cheer to the gas tank, when the pressure is 10kg, air compressor shutdown or unloading, when the pressure to 7kg when the air compressor and started, here there is a pressure difference, this process can make the compressor rest, to protect the air compressor.

  The motor drives the compressor directly to make the crankshaft produce rotating motion, driving the connecting rod to cause the reciprocating movement of the piston and causing the change of the cylinder volume. The change of pressure within the cylinder, the air inlet valve to make the air through air filter (muffler) into the cylinder during the compression stroke, the cylinder volume reduced, compressed air through the exhaust valve, the exhaust pipe, a one-way valve (check valve) into the gas tank, when the exhaust pressure reaches the rated pressure of 0.7MPa by the pressure switch control and automatic shutdown. Automatic connection start of pressure switch when the pressure of gas tank is down to 0.5--0.6MPa

  A pressure switch is a device that is combined with an electrical switch. When the preset fluid pressure is reached, the switch is connected. It is mainly applied to output alarm or control signal on industrial equipment such as power plant, petrochemical industry and metallurgical industry. It has important application in industrial field, it can prevent damage of important devices in production engineering, and avoid major production accidents.
